java - libgdx - Image setDrawable not working -

-

changing actor(image subclass) texture @ runtime doesn't work. texture argument of constructor call drawn. searched solution, nothing did work. last try looking code in image constructor, sets drawable und calls setsize().

circuitelement extends image

public class bulb extends circuitelement {     boolean on;     int x, y;      textureregion bulbon;     textureregion bulboff;      public bulb (int x, int y, int id, textureregion i) {         super(i);          on = false;         //this.x = x;         //this.y = y;         this.id = id;          textureatlas atlas = new textureatlas(gdx.files.internal("switch.pack"));         bulbon = atlas.findregion("bulbon");         bulboff = atlas.findregion("bulboff");         setwidth(bulbon.getregionwidth());         setheight(bulbon.getregionheight());         setbounds(0, 0, getwidth(), getheight());         debug();          this.addlistener(new clicklistener() {             public void clicked(inputevent event, float x, float y) {                 if (on) {                     on = false;                 } else {                     on = true;                 }                 system.out.println(on);             }         });     }      @override     public void draw (batch batch, float parentalpha) {         if (on) {             setdrawable(new spritedrawable(new sprite(bulbon)));             //setwidth(bulbon.getregionwidth());             //setheight(bulbon.getregionheight());             //setbounds(0, 0, getwidth(), getheight());             setsize(getprefwidth(), getprefheight());         } else {             setdrawable(new spritedrawable(new sprite(bulboff)));             //setwidth(bulboff.getregionwidth());             //setheight(bulboff.getregionheight());             //setbounds(0, 0, getwidth(), getheight());             setsize(getprefwidth(), getprefheight());         }     } }

i had call super.draw() in own draw-method, after calling setdrawable , setsize.

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...

sorting - opencl Bitonic sort with 64 bits keys -

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a...
